Integrated TODO into README.md
Added GdStack as a dependency

It is a part of libgd, I have just activated the feature
Added version information to pkgconfig dependencies
Succesfully changed to the GdStack framework from the GtkNotebook

This will be further transitioned to GtkStack when Gtk 3.10 goes stable
Started implementing load/save functionality
Created ag_chart_new_full() instead of ag_chart_new()
Changed AgWindow's moment to an AgChart for later saving functionality.
Removed GTK-Doc style documentation

It makes no sense. Some functions may remain having a documentation block, though.

Changed package name to Astrognome for prettier --version output
Renamed ret to chart in ag_chart_new()
NLS related fixes in main()
Added option --new-window to remotely open a new window.
Now adding all planets to the chart

The chart generating procedure will decide what to show and what not.
Since GNOME itself has a requirement for a slightly fast machine, it
is not very likely that it will cause speed issues.
Changed variable name self to app in AgApp methods
Moved command line options into main()

Global variables for this just didn't seem right.
Removed non-used struct print_data
Changed application_activate_cb() signature

Made it so casting is no longer needed inside.
